We've all heard about various services that let folks who've swilled a few too many Everclear-and-Hawaiian-Punch cocktails dial a number and have a sober driver show up to drive them home in their own cars (Top Gear has documented such a service in London, for example). However, the South Korean version of this service has the nation's 100,000 rent-a-designated-driver employees toiling in a Dickensian world of belligerent customers, rides hitched home from edge-city truck stops, and general harshness. The whole thing sounds like good material for a plaintive country song, Korean style.
